This isn't our first run-in with the Nun, after all.

The Conjuring Universe might not have the name recognition or the star power of something like the MCU, but that doesn't mean it isn't a self referential web of continuity and call acks that happen across different movies, pulled from different sources, over multiple years. If there's anything the 2010s have taught us about pop culture it's that we just can't get enough of a good shared cinematic universe.

The Nun is the fifth installment in the Conjuring lineup, after two official Conjuring movies, Annabelle, and Annabelle: Creation, meaning it has a ton of room to work in this particular playground. And work it does, as it follows the ill-fated adventure of a vatican employed "miracle hunter," Father Burke, and his newly assigned partner, Sister Irene (Taissa Farmiga) to investigate a mysterious suicide in a remote Romanian monastery. Of course, things don't go exactly as planned, and what Burke and Irene actually wind up finding is anything but a miracle. The monastery itself had been confining an ancient demonic evil that had since escaped its prison and was beginning to rain death and terror down on anyone who dared cross its path.

This wasn't the first time we'd come face to face with said demonic evil. Valak, the demon nun itself, has been featured in multiple Conjuring Universe installations with a featured role as the Big Bad of the Conjuring 2, and as an ominous and looming presence in Annabelle: Creation. Wheels within wheels of manipulation and deceit have placed Valak at the very heart of the Conjuring Universe's arcane web, and subtly built it up as one of the most destructive and dangerous forces in Ed and Lorraine Warren's life.

But we're not here to talk about the doom and gloom of Valak's spooky apocalyptic desires, ambiguous as they may be. We're here to talk about all the references, nods and Easter eggs The Nun managed to pack into this latest chapter of the Conjuring Universe. We've compiled a list of everything we caught, from classic horror shout outs to historical spooks. Click through the gallery to see them all, and let us know in the comments if we missed anything.
